BTW, to ape what Billybob is saying but from a lower end perspective, Sigma is also trying to fill niches where Canikon does not have much of a presence and I appreciate those efforts as my 3 lenses are all Sigmas:
18-35 f/1.8 not low end, but mid-grade and no competition anywhere for it
17-70 f/2.8-4 nothing like this anywhere and a good complement to the above
18-250 f/3.5-6.3 lots of other choices here but frankly, the Sigma was cheaper than the other options and seems not to have the lens creep that I've seen in the others. Which probably means I need to use it more and it'll loosen up more (too much) like the others. Fun lens in bright light.
I'll be getting the 50-100 f/1.8 assuming it performs well though the initial sample shots seem to have lateral chromatic aberration in the corners. Sharpness seems to be pretty good at f/1.8 but not as spectacular as the 18-35. Where the 18-35 really seems to be a prime-quality zoom, the samples from the 50-100 seem to be a very good quality zoom but not necessarily a prime replacement lens.
